Beit known that I, HIRAM JOSEPH HALLE, a citizen of the United States,residing` at Cleveland, in the county of Cuyahoga and vSta-te ofOhio,have invented a new and use-.

ful Extensible Platen for Type-Writing Ma-j chines, of which thefollowing is a specification.

My present invention relates to a platen for type-Writing machines ofthat class which print upon a sheet supported in a flat or spread-outcondition upon a flat stationary platen over which the machine ismovable both laterally and longitudinally. This type of machine,exemplified in Patents Nos.` 562,625 and 573,868 of R. J. Fisher, isgenerally intended for writing in books or on loose sheets and formaking up records and reports and copies thereof. Theflatplateniseq'uipped with main tracks or guides designed for the support ofa machine-frame movable longitudinally of the platen 'or in thedirection of line-spacing and supporting a carriage movf able on theframe transversely of the platen andequipped with Writing mechanism. yThese' tracks or y guides supporty the machine' for' movement to'anydesired position opposite" the printing area and are .also extendedloe-g youd theV printing area to support the machine outside of orfbeyond thewritinglsurface an'd over a platenextension.l This provisionfor` supporting' theniachine either directly above,`

or beyond the printing area constituted the broad novelty disclosed inmy Patent No. 621,660, dated March 21, 1899, and was intended tofacilitate the -displacement of the machine from the printing areaforthe pur pose of displacing, replacing, or adjusting the Work sheet orleaf. The retention of the work sheetor element in its proper positionis facilitated byvworkholding means associated with hinged track orguide sections longitudinally coextensive with the printing area of theplaten and movable away from the platen to permit the displacement orreplacement ot the work element after the machine has been moved backupon the fixed sections of the tracks or guides, and thereby positionedabove the platen extension beyond sys To this endvthe inventioncontemplates the equipment of the platen with a displaceable extensionnormally depending vertically from the rear end of the normal platenextension,'but capable of being presented in the horizontal plane of theplaten when an extension of the latter is desired This platen extensionwhen in its horizontal position is designed as a machine-support locatedbeyond the printing area of the platen, and is therefore provided withtracker yguide seca tions constituting continuations of the tracks V'orVguides of the platen proper. platen is elongated by the elevation of the"displaceable extension, the printing area is :increased by utilizingthe normal platen eX- 'When the tension as a continuation thereof, andpro- Vvision is therefore made for rigidly connecting the front and rearsections of the tracks or guides at the hinge-joints thereof and forswinging said tracks from an axis located adjacent to the front edge ofthe drop extension.

Other objects subordinate to that stated and various novel features ofconstruction will appear during the succeed/ing description ot theillustrated embodiment of my invention. Y

It has been stated that this invention owes its existence to the demandfor a platen adapted for various kinds ot work. While, therefore, theinvention, so far/as the presentapplication is concerned, comprehendsonly those instrumentalities whereby sheets of different lengths areaccommodated, l have nevertheless illustrated in the accompanyingdrawings a platen constructed in accordance with theinvention andequipped with various devices which facilitate the retention andmanipulation of dierent classesof work elementssuch, for instance, asthe leaf of a book, acard, a folded bill, an ordinary letter-sheet, andthe bills and subjoined sales-sheet employed in those billing systemswhich contemplate the entry upon the sales-sheet of successive carboncopies of the bills. It should be understood, however, that thiscomplementary equipment of the platen together with those supplementaldevices for properly positioning a carbon element or web to facilitatemanifolding are not herein claimed, although they involve many featuresof patentable novelty.

,'lhey are illustrated and described merely port or stand supporting theplaten 2, comprising, as usual, a metallic base 3,covered by a rubber orother suitable writing-surface 4.

It is sometimes desirable to elevate the platen for the purpose offacilitating the manipulation of the leaves of a book when the device isemployed in connection with this character of work element, and for thisreason said platen is hinged at its rear end, like the platen shown inmy Patent No. 621,660, above mentioned.. Instead, however, ot having adirect pivotal connection withl the front end of the platen extension,as in the patented construction, the platen has a hinge connection, asindicated at 5, with what may be termed a drop-frame 6, disposedvertically at the rear end of the platen and supported in any suitablemanner.

By preference the frame 6 is provided at its upper endand below theplane of the platen with guide'- rollers 7 and at its lower end withother guide rollers 8, the rollers 7 engaging a rail 9 and the rollers 8engaging a similar rail 10 The rails 9 and 10 are connected by one ormore rack-bars 11 and are designed to be raised and lowered in unisonwith a.v front rail 12, located in front of the stand 1 and supportingthe front end of the platen. The equipment of a stand with these railsfor raising and lowering the platen in order to facilitate the use ofthe latter in connection with the leaves of a book is common, as also isthe mechanism (not illustrated) for adjusting the rails vertically.

The specific construct-ion of the drop-frame 6 is beyond the purview ofthe present invention and 'for this reason need not be described indetail. It is sufficient tostate that this frame constitutes a supportto which the platen is hinged at its rear end and which serves t-headditional purpose of a support to whichis hingedly connected, asindicated at 13, an extension 14 of the platen. This hinged connectionis preferably effected by forming the drop-frame with a pair ofbearing-ears 15, received between similar ears 16, connected to thefrontend of the pl-aten extension 14 and constituting bearings for thepintles 17, one of which is indicatedin dotted lines in Fig. 4.

The extension 14 constitutes, when in its horizontal position, acontinuation of the platen 2, and while in the present construction itis connected to said platen by an intermediate supporting frame it isevident that it might be otherwise mounted at the rear end of theplaten-as, for instance, by being hinged directly thereto. Normally theextension 14 is disposed vertically, as indicated in Fig. 3, but when aplaten of addi'- tional or abnormal length is required is supported inthe horizontal plane of the platen by a swinging supporting-bracket 18,includinga vertically-disposed bearing-bar 19, having trunnions 20,received within suitable bearings in the top and bottom horizontalmembers of the drop-frame 6.

i yond the printing area forrthe support ofthe oi' the extension saidextension may be lifted.

slightly to disengage the head 2l`from the socket 22, and the bracket 18may then be swung around to a position at right angles to that shown inFig. 2 to permit the extension to drop to its vertical position.

The main tracks or guides 23, designed for the support of the travelingmachine-frame, extend continuously along the opposite side edges of theplaten and the extension 14 and project slightly beyond the front end ofthe platen and the rear end of the extension.4

These tracks or guides are toothed, as usual, for the greaterportion oftheir length for engagement With toothed-wheels constituting elementsofthe line-spacing mechanism of the machine and are composed of threesections-*to wit, what may he termed the eX- tension or auxiliarysections 24, rigidly.

connected to the extension let and designed to move therewith, the rearsections 25, whichare normally stationary and are located at oppositesides ofthe normal platen extension, and the front 'sections 26,disposed at opposite sides of the normal printing area of the platen andhingedly connected at their rear ends .to the front ends of the rearsections 25 by hinges 27. Normally the extensionl/i is dropped down atthe rear end of the platen, and the machine when not in use is` disposedover .the rear end of the platen, constituting the normal platenextension, and is supported by the rear track-sections 25. That portionofthe platen lying in advance of this normal platen extensionconstitutes the normal printing area, and the hinging of the fronttrack-sections 26 is designed to permit their elevation to facilitatethe displacement of a Work-sheet from the platen or its replacement oradjustment thereon when the machine has been moved back beyond thenormal printing area, as indicated in dotted lines in Fig. 8, the fronttrack-sections 26 being1 connected for movementin unison toward and awayfrom the platen bya transverse bar 28, as usual. This generalarrangement of the platen and of the main tracks or guides having hingedsections extending along the opposite sides of the printing area andstation- `ary sections for supporting the machine over the platenextension is quite ordinary; but, as has already been stated, theYprimary object of my invention, so far as the present application isconcerned, is to provide for the extension ofthe printing area withoutdis-I pensing-with a machine-support located be- -moved from the hinge.

lis

machine during the manipulation of the work. For this reason the reartrack-sections 25 are hinged at their rear ends, and suitable means isprovided for locking the front and rear track-sections 26 and 25 rigidlytogether in properly-alined positions, so that what are normally the xedand swinging sections of the main tracks or guides become swingingsections disposed along the opposite sides of an abnormal printing areaincluding both the normal printing area and the normal platen extension.When the printing area of the platen is thus extended L o include thenormal extension or machine-support, the eXtension let is swung to andsupported in its horizontal position to constitute a machine-support forthe reception of the4 machine when the latter is moved back beyond theabnormal printing area.

The manner of hinging the rear track-sections 25 is not material so faras the invention in its broader aspects is concerned, since the onlyrequisite is that they be capable of swinging from an axis beyond therear end of the normal printing area when an extension of such area isdesired. Inasmuch, however, as the present construction contemplates thehinging of the platen to permit the same to be swung up in a mannerdescribed in my patent'aforesaid, l have shown the track-sections 25provided at their rear ends with depending bearing-ears 29,7pivotallyconnected, as

contemplates the extension of one track-section and a device forconnecting such extension to the other track-section at a point retion,and one only need therefore be described.

IIO

The locks employed 'i The front end ofv the rear track-section 25 hasattached thereto a plate 3l, seated Hush 4with the under side of thetrack and extended beyond the hinge 27, connecting the front and rearsections. The extended portion of this Aplate is disposed for receptionwithin a recess 32, formed in the under side of the front tracksection26 and extending from the 'hinge 27, and adjacent to its end is providedwith an opening 33 for the reception of a head or pro- -jection 34,which tits-within the opening 33 mounted within a casing 38, formedbybending up and overA the outer side edge of the` plate 31.

When the front tracksection is swung down to its horizontal position inalinernentv with the rear track-section, the head 34 enters the opening33 in the plate 3l and serves to vhinge 27.

assist in preventing any lateral movement of the track-section in ahorizontal direction. When the parts are in this position, the angularend 36 of the latch-bolt 37 will be located in one end of thecounter-recess 35, and by moving-said bolt endwise the end 3b` may beslid over the head i4-that is to say, between the head 34 and the bottomof the recess 35-to effect the connection of the front track-sectionwith the extension of the reartrack-section at a point in advance of theThis movement of the latch-boltl is facilitated bythe provision at itsrear end ofa nger-piece 3S, which may be engaged by the finger-nail inan obvious manner. When the front and reary track-sections are thuslocked rigidly in alinement, they obvi-y ously constitute a singleswinging track-section hingedat the rear end of the platen or abnormalprinting area and capable of movement toward and awayfrom the platen tofacilitate ,the manipulation of the. work elements.

We have now seen that the platen is equipped with main tracks or guidescomprisingconnected front sections movable toward andvaway from theplaten and rear sections located beyond the normal printing area tosupport the machine while the front sections are manipulated and havinghinges located at their rear ends and locking devices for connectingtheir front ends rigidly with the front` sections, so that the hingedframe, including the track-sections and their connections, may swingupon an axis located beyond the normal axis of movement of said framewhen an Itr extension of the printing areais desired. may-be noted,however, that under some circumstances-as, for instance, whencomparatively narrow work-sheets are being used-it isnot necessary toelevate both rails, andit` .is therefore within the purview of thisinvention toconstruct only one rail or track in sections in them annerdescribed. We have also seen that the platen is equipped with an eX-tension retained in a horizontal plane to constitute a machine-supportin rear of the nor-v mal platen extension and designed to support themachine at a point beyond the abnormal printing area, including thenormal printing area and the normal platen extension y ing area. Thesemachine-stops are preferpoint slightly beyond its frontedge, so thatwhen the drop extension is down' the machine-stops will project slightlyabove the tracks or guides at the rear ends of the rear track-sections25 to arrest the machine in the position indicated in dotted lines inFig. 3. The specific construction of these machinestops 39 is notmaterial, nor is it essential that they be mounted upon the platenextension. lt issuficient if provision is made for the presentation of amachine-stop in position to arrest lthe machine over the normal platenextension or machine-support and for the withdrawal of said stop fromsuch position to permit the machine to travel back upon the dropextension when thelatter is in use. For instance, the extension insteadof' being dropped when not in use may be raised to an upright positionto' effect itsdisplacement and in such. position would constitute avmachine-stop located at the rear end of .the normal platen extension. Itwould also be possible-to locate thehinge ofthe eX- tension a shortdistance in rear of its front edge, so that the latter would projectupto constitute a machine-stopV when the eXtension is dropped. It isdesirable, however, to provide, as in the present construction, for theautomatic presentationof the machinestops 39 into the path of themachine when the platen extension 14- is dropped down and for theautomatic withdrawalof said stops when the drop extension is swung up,so that .the machine may travely back over the drop extension, Where itwill be arrested by the machine-stops 40 in the form of pins or pro--jections extending from the track-sections 24 adjacent to their rearends.

Having completed the description of that structure upon which thesubjoined claims are predicated, I shall now proceed to describe brielythe complementary equipment which renders the platen available fordifferent classes of work. It may be noted at this point, however, thatsome ofthe features ofthe platen equipment herein shown and hereinafterdescribed were not invented by me. On the contrary, thebilling stripsand slidey weredevised by John A. Smith, the card-guides and connectedtapes andthe follower-plate having a machine-operatedclamping orguarding member were invented by C. F. Laganke, and the carbon-rollcarried by the platen extension, the tension mechanismfor the tapes,andl the specific form of bill-slide or invoice-holder were invented byJoram Ziegler. To such featuresl make no claim. y

Along one side of the platen and outside of the adjacent track or guideisedetachably secured a slottedfgage-strip 41, equipped .with gage pinsor projections 42, adjustablelalong IOO the strip andidesigned tocoincide with and engage the file-openings of a sales-sheet 43,

disposed a billing-stri p 44, having detachable platen.

.equipped with a sliding work-holder or billconnection with one leaf,45, of a hinge 46, the other leaf, 47, of which is fixed to a projectingportion 48 of the platen ata point beyond the rear end of the gage-strip41. When attached as in use, the billing-strip is designed to swing downupon the gage-strip 41 with its upper edge substantially flush with thewriting-surface. inasmuch as it clamps the edge of the salessheet andprevents the latter from becoming disengaged from the gage pins orprojections 42, the upper ends of lhe latter being accommodated by oneor more slots 49 in the billingstrip.

AOrdinarily the sales-sheet, secured in the manner stated, completelycovers the Writingsurface of the platen and is designed to receive thetransferred copy or record-entry of successive bills as they 'are madeout ou the The billing strip 44 is therefore slide 50, havingwork-engaging devices-as', for instance, a pair of opstanding gageprojections or studs 51. The work-engaging projections of the bill-slideare adjustable to accommodate them to the file or binding holes sitionwith respect to the sales-sheet as to cause the copy or record-entry tobe made directly below or following the copy of the preceding bill.During the manipulation of the sales-sheet and bill to properly positionthem upon the platen the swinging sectionsof the main tracks or guidesare sustained in an elevated position and are subsequently swung downupon the work-sheets to assist in their retention, the clamping actionof the tracks being augmented by one or more spring-clips 52, carried bya track and extending'inwardly therefrom.

Obviously the reproduction of the bills upon the sales-sheetnecessitates a transfer- 'ring element between the bill and sheet. Forthis purpose a loose carbon-sheet or one secured by the billing-stripmight be employed. I have, however, shown the platen equipped with acarbon element or web 53, extending between carbon-carriers 54 and 55,mounted at the rear'end of the drop extension 14 and at the front end ofthe platen, respectively. As the carbon element becomes worn it isunwound from the delivering-roll upon the carrier 54 and is'wound uponthe. front carrier 55 by the rotation ofthe latter through the medium ofthe thumb-wheel, suitable guide-rollers 57, 58, and 59 being mounted' atthe opposite ends of the drop extension 14 and at the front end of theplaten, respec- It will he noted that the location of It serves thepurpose of a work-holder,A

drop extension permits the carbon element` to be moved with equalfacility Whether the drop extension is up or,down,as in the latterposition this roller will be located at the upper edge of the extensionto guide'the web in an angular direction. Y

While the front guide-roller 59 and the front carbon-carrier 55 arelocated at the front end of the platen, theyare not directly carriedthereby, but are sustained by the track-frame for movement therewiththrough the medium of suitable brackets, as shown.

Atthe side of the platen opposite the billing-strip 44 is located alaterally-adjustable tracks and secured at their front ends to card-Aguides 64 and at their rear ends to slides 65. These tapes are designedto be adj usted laterally to present them'at the edges of worksheets ofdifferent widths, and the card-guidesY 64'are therefore slidably'securedto the framey bar 28, provided with a scale or series of graduationscorresponding with the graduations upon a transverse tension-bar 66,slidably supporting the slides 65 and constantly urged rearwardly bysprings 67, attached as shown. These strips or tapes are designed toguard theopposite edges of cards properly positioned upon the platenwith the aid of the card-guide, and when folded bills employed inconnection with some billing systems are to be written uponktheright-hand tape is received within the folded edge or bight of the bill,with the other strip or tape disposed to guard the opposite edgethereof. employing a pair of stripsor tapes, as shown, the platen may beequipped with one onlyif it is simply desired to provide for theengagement of the fold or bightolj a bill, for instance.

The platen is further equipped with a transversely-disposedprotecting-plate 68, having its opposite endsv slidably received withinthe grooves 69, formed in the inner faces of the tracks to permit theadjustment of the plate lengthwise of the platen. Whiletheprotecting-plate is capable of being advanced over IIO Instead of thetop edge of the sheet imposed upon the platen and is therefore equippedwith a movable Work holding or guarding member 68, carried by the frontends of operating-levers 70, fulcrumed upon the protecting-plateand.having their rear ends 71 extending upwardly into the path of ,thefront bar of the machinefraxne. When the machine is moved back from overthe work, the frame-bar is designed to contact with the rear ends of thei operating-levers 70 for the purpose of swing- I urged in one directionby a spring 74 and having terminal lifting-arms 75, provided with smallantifriction-rollers 76, which bear against the under sides ofthe tracksorguides. The power of the spring 74 is just sufficient tocounterbalance the swinging frame comprising the tracks or guides andtheir connections, so that said frame may be easily manipulated by theoperator. It is also desirable to protect the carbon-rolls by detachableguards 77, as shown.

Ordinarily the drop extension 14 is located in its inoperative position,as shown'in Fig. 3, and the front track-sections 26 are free to swingindependently of the rear track-sections 25. AThat portion of the platenlying l the rear track-sections.

between the rear track-sections 25 therefore constitutes the normalplatenextension, to a position over which the machine is moved, as shownin dotted lines, when it is -desired to elevate the swinging frame forthe purpose of displacing the work element or elements from or replacingor adjusting the work within the normal printing area defined by thatportion of the platen lying in advance of When the platen is used inthis manner, the machine is stopped in its proper position by themachine-stops 39, secured at the front end of the drop extension. When,however, it is desired to write upon work-sheets of abnormal length,

the drop extension is raised to its horizontal position, where itisretained by the bracket 18,. and the front and rear sections ofthevtracks or guides are rigidly connected in 'i alinement by the lockingdevices shown in Figs. 7 and 8. The raising of the Adrop extensionwithdraws the machine-stops 39 from the path of the machine and presentsthe auxiliary track-sections 24 in alinement with i the track-sectionsdisposed above the platen.

The machine may now be moved back upon the extension beyond the rear endof the platen, where it will be arrested by the machine-stops 40. Theswinging frame will then comprise the front and rear track-sections,movable in unison toward and away from the platen and swinging from anaxis located at the rear end of the normal platen extension, which thusbecomes a part of the printing area of the platen.

`In conclusion it may be stated that the.

platen extension 14 constitutes both a machine-support and adisplaceable supplemental platen extension. Viewed merely as amachine-support it embraces a wide range of equivalents, lbecause theinvention in one aspect thereof comprehends the broad idea of providinga machine-support of any character whatsoever located beyond the mainbody of theplaten and displaeeaole from its normal position either byactual removal or by a mere change of position. The expressiondisplaceable machine-support used in the claims is employed in thisbroad sense. Considered in another aspect, however, the extension 14constitutes a displaceable continuation or section of the main body ofAthe platen, since while it is primarily designed to perform the functionof a machine-supportit is nevertheless capable of being and under someconditions is designed to be utilized for the support of a work elementor a portion of a work element, upon which a limited amount of mattermay be printed by a machine located above the extension. In anotheraspect, therefore, the invention will be seen to comprehend a sectionalplaten, each section of which-is capable of displacement from its normalposition whether by actual removal or by such movement as will displaceit from that position which it normally assumes.

I make no claim to the subject-matter disclosed and claimed in theeopending application ofJohn A. Smith, Serial No. 67,346, thework-retaining devices being herein illustrated for the sole purpose ofshowing a fully equipped platen.

It is thought that from the foregoing the construction and mode ofmanipulation of the platen, as Well as the advantages accruing from itsuse, will be readily understood by those skilled in the art; but sincetheinvention in its broader aspect is of sufficient scope to includemany constructions other than that described I wish to be distinctlylinderstood as reserving the right to effect such changes,modifications, and variations of the illustrated structure as may fallproperly within the scope of the protection prayed.
